Now, it is plain from the foregoing that, though women's business in the world is of such a character that it inevitably leads to physical degeneration, her constant need to overcome the effects of this degeneration by cunning produces constant mental activity, which, by the law of exercise, should produce, in turn, great mental efficiency. This conclusion, in part, is perfectly correct, for women, as a sex, are shrewd, resourceful and acute; but the very fact that they are always concerned with imminent problems and that, in consequence, they are unaccustomed to dealing with the larger riddles of life, makes their mental attitude essentially petty. This explains the circumstance that despite their mental suppleness, they are not genuinely strong intellectually. Indeed, the very contrary is true. Women's constant thought is, not to lay down broad principles of right and wrong; not to place the whole world in harmony with some great scheme of justice; not to consider the future of nations; not to make two blades of grass grow where one grew before; but to deceive, influence, sway and please men. Normally, their weakness makes masculine protection necessary to their existence and to the exercise of their overpowering maternal instinct, and so their whole effort is to obtain this protection in the easiest way possible. The net result is that feminine morality is a morality of opportunism and imminent expediency, and that the normal woman has no respect for, and scarcely any conception of abstract truth. Thus is proved the fact noted by Schopenhauer and many other observers: that a woman seldom manifests any true sense of justice or of honor. It is unnecessary to set forth this idea in greater detail, because everyone is familiar with it and proofs of its accuracy are supplied in infinite abundance by common observation. Nietzsche accepted it as demonstrated. When he set out to pursue the subject further, he rejected entirely the Schopenhauerean corollary that man should ever regard woman as his enemy, and should seek, by all means within his power, to escape her insidious influence. Such a notion naturally outraged the philosopher of the superman. He was never an advocate of running away: to all the facts of existence he said "yes." His ideal was not resignation or flight, but an intelligent defiance and opposition. Therefore, he argued that man should accept woman as a natural opponent arrayed against him for the benevolent purpose of stimulating him to constant efficiency. Opposition, he pointed out, was a necessary forerunner of function, and in consequence the fact that woman spent her entire effort in a ceaseless endeavor to undermine and change the will of man, merely served to make this will alert and strong, and so increased man's capacity for meeting and overcoming the enemies of his existence.
